Demonstrate how to create a cube and a sphere using Blender's modeling primitives.

Creating a cube and a sphere using Blender's modeling primitives is a straightforward process that involves the use of basic shapes to form more complex objects. Blender provides several modeling primitives, including cubes and spheres, which serve as the foundation for many 3D models. Here is a step-by-step demonstration of how to create a cube and a sphere using Blender: Creating a Cube: 1. Open Blender: - Launch Blender and make sure you are in the default "Layout" workspace. 2. 3D Viewport: - Ensure that you are in the 3D Viewport, the main workspace for modeling and manipulation. 3. Add a Cube: - Press `Shift + A` to open the Add menu. - Select "Mesh" from the menu. - Choose "Cube" from the submenu. 4. Manipulate the Cube: - The cube is added to the center of the 3D Viewport. - Use the following controls to manipulate the cube....
